练习：
1. A) looking B) seeing C) seeking D) feeling
2. A) below B) underneath C) with D) under
3. A) ruled B) bombarded C) captured D) visited
4. A) investigate B) attack C) shoot D) confront
5. A) named B) called C) known D) dubbed
标准答案：B,C,D,A,C
解 析：1.B see和look这两个词词义相关， 因此首先重点关注。空格前面出现了动词saw(see的过去时态)， 因此 B是答案的可能性较大(提示1：上下文的用词特点(上下文常常通过使用同一词汇/近义词/词汇/反义词形成上下文意义的衔接))。look是不及物动词，而see 既可用作及物动词也可用作不及物动词。空格处的动词是及物动词，引导定语从句的连接词充当从句中谓语动词的宾语， 因此B是答案。
考点：考察近义词的辨析
2.C 四个词都是介词。其中below、underneath和under是方位介词，这三个介词互为近义词，因此彼此排除掉(提示2：备选项中出现的近义词词组通常是干扰项)，因此答案只能是with(with是方式介词)。With所在的句子结构说“...以碟子飞速掠过水面的移动方式飞着”。
考点：常见介词的基本用法。
3.D 选项D是文章主题词(visitors)的家族词汇，因此D可能是答案(提示3：文章主题词/文章主题词的近义词/文章主题词的家族词汇可能是答案)。第三段的第一句话(Military(军事的) investigations(调查) found(发现) no evidence(证据) of visitors(客人) from outer space(外层空间).)说“军事调查并没有发现能证明从外层空间来了客人的证据”，由此判断空格处用visited上下文意义呼应。
考点：文章主题词/上下文意义衔接词
4.A 空格处需要出现不及物动词， 因此首先排除D(及物动词)。 该句说“不久由于出现了这么多的目击事件， 以至于美国军方开始...”, 根据该句句意判断A(调查)出现在空格中最恰当。
